Mobile Manipulator for Construction Work


Features of the Hot-Line Work Robot
  • Mobility...........Capable of moving to any work site
  • Vibration
    Compensation......At ease with objects on poles that vibrate and move irregularly
  • Insulation.........HV insulation makes it possible to work in rainy weather
  • Compact...........Mounted on as small a vehicle as possible to avoid obstructing traffic

  • The ground operation robot "PhaseII" was developed in which the operator can conduct distribution work remotely from within the cabin on the ground. (4 of this type were deployed by the end of 1993.)

Manipulator&Operators Cabin phase 2 Power Manipulator


Development Concept
  • To secure a comfortable working environment even under severe conditions such as rain, intense heat, and cold by complete elimination of manual hot-line work on poles and at heights.
  • To improve work efficiency by automation.
  • To improve electric supply reliability through implementing a uniform high quality of construction by eliminating the problem o differing manual work standards.

Result of technical development
  1. Revolution for other industries
    • Trend for adoption of the techniques not only in the domestic but also in others, such as the communication, transportation, fire fighting, and construction industries internationally.
  2. Technical progress
    • Contribution to wide technical progress in industry
    • Encouragement for full automatic system development in distribution work
Future Subjects
  • Development of a fully automatic robot, "PhaseIII"
  • Development of distribution facilities suited for robotic applications (materials and construction methods)
